When the glove knitting area is finished, the projection 1121 on the breakpoint-type needle selection strip 112 jacks up the needle selection bird sheet 2 so that the needle jack 3 connected with the needle selection bird sheet drives the knitting needle 4 to knit, and the needle selection bird sheet 2 is not jacked up at the interval so that the knitting needle 4 does not knit, because of the equidistant arrangement of the breakpoint-type needle selection strip 112, after a plurality of loop courses are knitted at the lockstitch, the lockstitch knitting area is naturally bent, that is, the upper end loop of the fabric at the lockstitch is turned back to the lower end loop to make further preparation for lockstitch at the tail part of the rib main body part of the glove.
After several loops of course are knitted at the lockstitch, the driving mechanism drives the needle selection cylinder body 11 to reversely rotate and return to the working position of the continuous needle selection bar 111, at this time, the knitting needle 4 at the original position returns to the action state, the upper end loop and the lower end loop at the lockstitch are knitted together, and the needle at the upper end of the fabric at the lockstitch which is folded back to the base part of the lockstitch is knitted together to form the tubular hemming-shaped fabric. It should be noted that, due to the equidistant arrangement of the breakpoint-type needle selection bars 112, after the stitch course is knitted for several cycles, the stitch knitting region is naturally curved, that is, the upper end stitch of the fabric at the stitch is folded back to the lower end stitch.
In this embodiment, in order to facilitate needle passing during overlocking, a top surface of the projection 1121 is made into an arc surface, and preferably, the projection 1121 may be a cylinder, and an end surface of the cylinder is arranged in parallel with an end surface of the needle selecting cylinder body 11. And the length of the interval of the breakpoint-type needle bars 112 is the same as the transverse length of the projection 1121 and corresponds to one selector jack 2.

When the overlock knitting is performed, the presence of the convex block 1121 on the breakpoint-type needle selection strip 112 enables the corresponding knitting needle 4 to normally knit the attached loop, and at the position where the convex block 1121 is not installed, the corresponding knitting needle 4 can always stay at the original position with the loop, so that the phenomena that part of the knitting needles 4 are knitted and part of the knitting needles 4 stay occur.
As shown in fig. 2, in the course of practical use, the needle selector is attached to a glove knitting machine to perform needle selection. The glove knitting machine comprises a rack, a front needle selecting device and a rear needle selecting device, wherein the front needle selecting device and the rear needle selecting device are arranged on the rack in a front-back symmetrical mode, and the front needle selecting device and the rear needle selecting device are the same needle selecting devices provided in the first embodiment.

Fig. 3 is a development view of the front needle selecting roller 1 in the front needle selecting device.
The method specifically comprises the following steps;
s1, a driving mechanism drives a needle selection roller 1 to rotate until a continuous needle selection strip 111 is opposite to a needle selection bird sheet 2, and finger parts and palm parts of the glove are woven in a common knitting mode. Wherein, the little finger, ring finger, middle finger and index finger are firstly knitted, then the four palms and the thumb are knitted, and then the five palms are knitted.
The re-driving mechanism drives the needle selecting roller 1 to rotate until the continuous needle selecting strip 111 is opposite to the needle selecting bird sheet 2, and the rib top of the glove is knitted by high and low needles or flat needles.
In this embodiment, the rib (plain needle) continuous selector 1111 or the rib (high-low needle) continuous selector 1112 is selected according to actual needs to knit the rib knitting area 120. When the rib top is knitted, the yarn and the elastic yarn are combined for knitting.
S2, the driving mechanism drives the needle selecting roller 1 to rotate until the breakpoint needle selecting strip 112 is opposite to the needle selecting bird sheet 2, the tail end of the rib top part is subjected to serging knitting, a serging knitting area is automatically curled inwards, and the serging knitting area is knitted by adopting single-covered spandex.
And S3, the driving mechanism drives the needle selecting roller 1 to reversely rotate, so that the needle selecting roller 1 returns to the continuous needle selecting strip 111 to be opposite to the needle selecting bird sheet 2, and the inward curled overlock knitting area is locked. Wherein, the combination of single-covered spandex and rubber string is adopted for weaving during locking.
When the overlock crimp knitting is performed, the presence of the convex block 1121 on the breakpoint-type needle selection strip 112 enables the corresponding knitting needle 4 to normally knit the attached loop, and at the position where the convex block 1121 is not installed, the corresponding knitting needle 4 can always stay at the original position with the loop, so that the phenomena that part of the knitting needles 4 are knitted and part of the knitting needles 4 stay occur. It should be noted that, due to the equidistant arrangement of the breakpoint-type needle selection bars 112, after the stitch course is knitted for several cycles, the stitch knitting region is naturally curved, that is, the upper end stitch of the fabric at the stitch is folded back to the lower end stitch.
After knitting several loops at the tail of the rib top, the driving mechanism drives the needle selection cylinder body 11 to turn over and return to the working position of the continuous needle selection strip 111, namely the rib top knitting area 120, at this time, the knitting needle 4 in the original position returns to the action state, the upper end loop and the lower end loop at the serging position are knitted together, the needle at the upper end of the fabric at the serging position returning to the base of the serging position is knitted together to form the cylindrical hemmed fabric, and finally, the serging is finished.
According to the glove knitting process, the breakpoint needle selection strips 112 are arranged on the needle selection cylinder, and the continuous needle selection strips 111 are matched to realize automatic welting of glove knitting, so that the glove blank knitting welting is integrally formed, and the manual welting step is omitted, so that the working efficiency is improved, the appearance of the produced gloves is smoother, and the product quality is more stable.
